This will help avoid slipping in the test. Place the tab in the grip and apply a steady load at a test speed of 50 mm 2. They can be equipped with a selection of interchangeable grip jaw faces in various sizes and choice of surfaces including smooth ground, rubber-coated and serrated. Line contact and special coated faces are also available. Subscribe to Our Newsletters. XyLive is the best choice to enable the test engineer to visually monitor the progress of the test vs the data on the computer screen.

We use cookies to improve your browsing experience. It is important to review ASTM D in order to fully understand the test setup, procedure, and results requirements.

Secrets of Reliable Testing. Next, take the assembly out of the oven and take it apart to create six test specimens.

Email addresses must contain the symbol. They are designed with standard and optional features that increase testing efficiency and improve the testing experience for the operator.

The standard calls out several test types related to rubber adhesion strength; however, Methods A and B are the most common. The sample also lends itself to testing the effectiveness of different processing techniques and various adhesive systems.

This geometry promotes interfacial failures. Adjustable data acquisition rates allow the user to ensure they are capturing all the desired peaks and troughs throughout the entire test. Pneumatic grips are active in that they maintain the same gripping force even as the specimen necks down. This ensures that the line of tensile force remains concentric with the grip body.

The dual – acting design of series grips means that jaw faces can be adjusted to accommodate different specimen thicknesses. The adhesion values are obtained by measuring the force in an axial direction that is necessary to separate the bonded rubber from the metal component.

The test machine should be equipped with swivel joints above and below to ensure uniformly distributed tensile force tensile force through the specimen assembly. Next Checking to see if you are a returning visitor….

Software for Series Systems. Pneumatic grips also provide constant clamping force throughout the test to avoid specimen slippage.

ASTM D – 14 Standard Test Methods for Rubber Property—Adhesion to Rigid Substrates

Maintaining unidirectional force throughout the process of peeling from a substrate. Maintaining unidirectional force throughout the process of peeling from a substrate.

We also recommend serrated jaws on your grips to avoid sample d49. Bluehill Universal Brochure Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience. As force is applied in one direction the material shrinks in the orthogonal direction. Each specimen will consist of a rubber puck with 2 pieces of metal.

Place the tab in the grip and apply a steady load at the rate of 50 mm 2. Peel fixtures provide a condition of use to measure the bond strength between laminated surface coatings, atm, packaging, d4299 their rigid backings, as well as other bonded structures.

ASTM D429 Rubber Property – Adhesion to Rigid Substrates

It is important to review ASTM D in order to fully understand the test setup, procedure, and results requirements. This test machine is suggested because it has a long travel, which is preferred because rubber coating tests to enlongate quite a bit when stretched. First, pull a quality control test piece from each molded batch to determine that per cent adhesion is obtained prior to environmental exposure or laboratory storage with a pre-strain.

Before the load is applied, strip the rubber from the metal plate by using a sharp knife. Concrete, Asphalt and Rock. Loads as high at 10, pounds can be common. ASTM D determines the adhesion strength of rubber to rigid materials, such as metals. Peel fixtures provide a condition of use to measure the bond 4d29 between laminated surface coatings, films, packaging, and their rigid backings, as well as other bonded structures.

Email addresses can only contain letters, numbers and the following special characters: Some of the tests are aimed at shear strength of that adhesion interface. Most of the tests involve orthogonal tensile strength or peel strength qstm the adhesion interface.

This test is often used to find which adhesive is best for the given rubber. WaveMatrix 2 for Dynamic Testing.
